This earth dam stands at 8 feet in height and stretches over 750 feet in length, impounding Mill Creek to create a storage capacity of 83 acre-feet. Despite its historical significance and primary purpose for water supply, the dam is currently assessed to be in poor condition with a significant hazard potential.
Regulated by the New Jersey Department of Environmental Protection (NJDEP), the dam undergoes regular inspections, with the last assessment conducted in April 2021. The dam's emergency action plan (EAP) status and risk management measures remain unreported, raising concerns about its ability to withstand potential emergencies and natural disasters. With Congressman Jeff Van Drew representing the area in Congressional District 02, efforts to address the dam's structural integrity and risk mitigation strategies may be crucial for safeguarding the surrounding community and water resources.
